口腔临床英语对话(音频) 第12期:根管治疗法(3)

I have a root canal filling in one of my teeth. The tooth is changing color. Can anything be done about it?
我有一颗牙在牙根管里补过。现在这颗牙变了颜色,有什么办法可以解决?

Sometimes a tooth with a root canal filling will change color.
牙根管补过的牙有时会变色。

I can treat it by bleaching it with superoxol (30%H2O2).

If the crown of the tooth is weak it would be better to make a porcelain, acrylic, or ceramic crown.

If the crown of the tooth is strong, I'd rather bleach it. Bleaching a tooth isn't very difficult.

What is the first step, Doctor?
医生,第一步怎么做?

The first step is to remove all of the old filling.

A rubber dam is needed to prevent the superoxol from burning the gingival.

There's no discomfort associated with this technique.

The tooth might be a very light color after it's bleached.
